Hi Ryan, The most likely reason for what you are experiencing is that your platens are getting too warm and the contact with the screens is pushing the ink temperature in them close to the gel point. When the weather is warm, the ink starts out at your room temp of 95. Therefore, when you add the warm platens to that 95 it does not take long for the ink to get warm enough to start gelling. This would happen with any ink. The solution is to minimize the temperature build-up in the platens in the first place. As your shop temp increases, the amount of flash energy that is necessary decreases. If this situation is happening on a manual press, cut back on the time you flash. If it is on an auto, either cut the temp or the time or both. Even on a cool day, it is important to minimize flash energy as the platens warm. Flashed ink only wants to be gelled, not cured. Let me know how it goes. Mike | ||
